A Boston man who has maintained his innocence through nearly four decades behind bars was granted his freedom after Suffolk, MA prosecutors admitted his 1981 murder conviction was tainted by discredited witness identification and police tactics. “To quote Sam Cooke, ‘it’s been a long time coming,’ ” Frederick Clay said after walking out of the Suffolk Superior courtroom yesterday. “It’s been 38 years for something I didn’t do. I’m overwhelmed and sort of nervous.”

Clay, 53, emerged from the Boston courthouse with his arms raised and a wide smile on this face, having last experienced freedom when Jimmy Carter was in the White House and “Bad Girls” by Donna Summer was at the top of the charts. He was convicted of the 1979 execution-style murder of 28-year-old cab driver Jeffrey Boyajian, who was shot five times in the head at a Roslindale housing project.

“From day one, they told me I was facing natural life in prison,” Clay told reporters, “and that scared me. But I was not going to voluntarily put myself in prison for something I didn’t do.” Professing his innocence cost Clay at his first parole hearing in 2015, when the three board members who denied his release wrote that he had “yet to accept responsibility for his actions.”

One of the witnesses to the crime said he was sure about Clay’s guilt after being hypnotized by police, then a widely-accepted practice thought to enhance recollection. A second witness ID’d Clay after being promised he and his family could be relocated from their housing project if he helped investigators. Another man convicted in the slaying, James Watson, is still behind bars and prosecutors remain confident of his involvement.

Boyajian’s brother Jerry spoke in support of releasing Clay.“All my family has ever wanted was justice for my brother,” Boyajian said, recalling his older brother as a “jock” with a great sense of humor. “I really feel that justice failed Mr. Clay and, in that respect, it also failed my brother.”
